/* Layout: the page is the "Register Interest" sheet from the WhatsApp journey. A sticky top bar
   (close + title), a scrolling body, and a sticky footer holding the main button. On phones it
   fills the screen; on wider screens it sits as a 440px card on the teal brand ground.
   The page commits to one branded light look, so there is no dark variant. */
